// Generated by strudelify. One cycle = one bar.
// note: metre changes (4/4 at bar 1, 2/4 at bar 29, 4/4 at bar 30, 3/4 at bar 58, ...) are rendered on a constant 4/4 grid of one bar per cycle
// note: Full arrangement: all 84 bars on a 16-step grid, each part at one level; ghost notes are separate "_soft" parts. Source detail keeps the original performance.

// A part's distinct bars are riffs (A, B, C...) played in order: edit a riff to change every repeat.
